Mary Hilde Ruth Bauermeister (born 7 September 1934) is a German artist who works in sculpture, drawing, installation, performance, and music. Influenced by Fluxus artists and Nouveau Réalisme, her work addresses esoteric issues of how information is transferable through society. "I only followed an inner drive to express what was not yet there, in reality or thought", she said of her practice. "To make art was more a finding, searching process than a knowing." Since the 1970s, her work has concentrated on the themes surrounding New Age spirituality, specifically geomancy, the divine interpretation of lines on the ground.
